But in actual work, as an auxiliary part of the mold, the lock plate is not taken seriously during use, and because of its complicated disassembly and assembly, after the mold is installed on the injection molding machine, the disassembled lock plate can be placed randomly. The phenomenon that the locking template is often lost will affect the next handling of the mold
Occasionally, the mold has been damaged due to careless handling

Embodiment Construction
[0009] See figure 1 , figure 2 , image 3 , which includes a front template 1, a rear template 2, and a lock template 3. The lock template 3 is provided with a front mold positioning hole 4 and a rear mold positioning hole 5. The front mold positioning hole 4 is set with a rotating sleeve 6, and the fixing screw 7 runs through it. The rear thread of the rotating shaft sleeve 6 is fastened to the front template 1, and the lower side of the rear mold positioning hole 5 of the locking template 3 is provided with a threaded through hole 8, which is connected to the rear mold positioning hole 5, and the threaded through hole 8 is internally threaded A connecting bolt 9 is connected, and the part of the connecting bolt 9 facing the positioning hole 5 of the rear mold has a blind hole 10, and a spring 11 is arranged in the blind hole 10, and a wave bead 12 is mounted on the end of the spring 11 near the positioning hole 5 of the rear mold. The outer edge surface of the movable pul...

The invention provides a structure for a locking formwork component of a mould, which is simple in structure and is not easily lost, thereby having no influence on the carrying of the mould. The structure comprises a front formwork, a rear formwork and a locking formwork, and is characterized in that a front formwork positioning hole and a rear formwork positioning hole are formed on the locking formwork; a rotating shaft sleeve is sleeved in the front formwork positioning hole; a fixing screw passes through the rotating shaft sleeve and then is fixed with the front formwork in a threaded form; a threaded through hole is formed in the lower side of the rear formwork positioning hole of the locking formwork; the threaded through hole is communicated to the rear formwork positioning hole; a connecting bolt is in threaded connection with the interior of the threaded through hole; a blind hole is formed on a part facing to the rear formwork positioning hole, of the connecting bolt; a spring is arranged in the blind hole; a bead is resisted against one end of the spring close to the rear formwork positioning hole; two circles of positioning slots are arranged on the outer edge of a moveable pull pin; and the two circles of positioning slots are respectively a locking positioning slot and an unlocking positioning slot.
Description
technical field [0001] The invention relates to the structural technical field of injection molds, in particular to the locking plate assembly structure of the mold. Background technique [0002] The finished mold needs to be moved frequently during use and mold maintenance. In order to ensure the safe handling of the mold, a locking plate is designed on the mold to connect the parting parts of the front mold and the rear mold into one body to ensure the safe handling of the mold. But in actual work, as an auxiliary part of the mold, the lock plate is not taken seriously during use, and because of its complicated disassembly and assembly, after the mold is installed on the injection molding machine, the disassembled lock plate can be placed randomly. It often happens that the locking template is lost, which affects the next handling of the mold. Occasionally, the mold has been damaged due to careless handling. Contents of the invention [0003] In view of the above ...
